A senior member of the Syrian Ahrar al-Sham rebel group was killed along with six other fighters on Tuesday in a double suicide bombing in northwestern Syria, a monitor said.

No group claimed responsibility for the attack, but the Syrian Observatory for Human Rights said it was believed to have been carried out by a group linked to the Islamic State group.

Iraq's foreign minister on Tuesday sought "uninterrupted" military support from neighboring Turkey in its fight against jihadists from the Islamic State group.

"The presence of Daesh constitutes a threat not only to Iraq but also to countries in the region as well as Turkey," Ibrahim al-Jaafari told a joint news conference in Ankara with his Turkish counterpart Mevlut Cavusoglu, using a pejorative name for IS.

Thousands of Ethiopians and other migrants are flooding into war-torn Yemen, the United Nations said Tuesday, with many of them tricked by smugglers into believing the fighting there is over.

Johannes Van Der Klaauw, the U.N.'s Humanitarian Coordinator for Yemen, said 37,000 migrants had arrived in the impoverished country this year -- 10,500 of whom came after a Saudi-led coalition launched air strikes on March 26 in a bid to halt the advance of Iranian-backed militants who drove President Abedrabbo Mansour Hadi into exile.

Prime Minister Benjamin Netanyahu said Tuesday after world powers reached a historic nuclear deal with Iran that Israel was not bound by it and signaled he remained ready to order military action.

Netanyahu's harsh criticism of the agreement came after he warned for months that the deal being negotiated would not prevent Iran from acquiring nuclear weapons.

Iraq's army and allied paramilitaries attacked Islamic State group positions around Ramadi Tuesday in their latest push to recapture the Anbar capital from the jihadists, commanders said.

The authorities announced a major offensive to "liberate Anbar" on Monday, hours after the U.S.-led coalition launched a record number of air strikes near Ramadi.

The United Arab Emirates Tuesday welcomed the historic nuclear deal agreed by world powers and Iran, with an official saying it could turn a "new page" for the Gulf region.

"Iran could play a (significant) role in the region if it revises its policy and stops interfering in the internal affairs of countries like Iraq, Syria, Lebanon and Yemen," a UAE official said in the first reaction from the Gulf Arab monarchies to the Vienna accord.

To critics, lifting sanctions on Iran under an historic deal reached Tuesday will help its ability to foment unrest in the Middle East, but some experts say the nuclear issue has become a sideshow to more immediate crises in the region.

After years of negotiations, climaxing in an 18-day marathon in Vienna, world powers secured a deal with Tehran aimed at ensuring Iran does not obtain the nuclear bomb.

Syrian President Bashar Assad congratulated key ally Iran Tuesday on reaching a nuclear deal with world powers, calling the agreement a "great victory".

In a message to supreme leader Ayatollah Ali Khamenei, Assad said he was "happy that the Islamic Republic of Iran has achieved a great victory by reaching an agreement", state news agency SANA reported.

Kuwait charged 29 people Tuesday over the suicide bombing of a Shiite mosque last month, claimed by the Islamic State group, that killed 26 people and wounded more than 200.

The attack, carried out by a Saudi, was the worst in Kuwait's history.

The extremist Islamic State group has gained ground against the Syrian army in a major northeastern city, a monitor said Tuesday, after three weeks of clashes that killed 170 people.

On June 25, IS seized two southern neighborhoods in Hasakeh from pro-government forces, who share control of the city with Kurdish militia.
